Problems solved by technology

Compared with organic antibacterial agents, these inorganic antibacterial agents are non-volatile and non-decomposing, so the antibacterial effect lasts longer. However, inorganic antibacterial agents are generally powder antibacterial agents, which are prone to water turbidity and are not easy to recycle.

Abstract

The invention discloses a water treatment anti-bacterial material and a preparation method thereof. The water treatment anti-bacterial material is prepared from the following components in parts by weight: 50-60 parts of aluminum sulfate, 15-20 parts of polyving alcohol, 10-12 parts of acetate fiber, 3-5 parts of hydroxymethyl cellulose, 3-5 parts of clay, 3-5 parts of starch phosphomonoester, 2-3 parts of polymeric ferric sulfate, 1-3 parts of calcium phosphate dibasic dehydrate, 0.5-1 part of dimethylol urea, 0.05-0.2 part of tetraglycidyl xylenedi-amine and 0.02-0.2 part of imarcaptoacetate dioctyltin. The invention further provides a preparation method of the water treatment anti-bacterial material.

Description

technical field [0001] The invention belongs to the field of water treatment materials, in particular to a water treatment antibacterial material and a preparation method thereof. Background technique [0002] With the growth of population and the development of industry, the shortage of water resources, especially the phenomenon of water quality-type water shortage is becoming more and more serious, and the role of sewage treatment technology in production and life is also increasing. [0003] The quality of water directly affects the environment and people's health, especially organic pollutants, which accelerate the growth and reproduction of algae in the water and accelerate the deterioration of the water. [0004] Antibacterial agents used in water treatment can be divided into organic antibacterial agents, inorganic antibacterial agents and natural antibacterial agents. Known inorganic antibacterial agents include apatite, zeolite, glass, zirconium phosphate, silica ge...
